Red Synton Syrinx Audio Demo

video upload by Edwin Kiddo

"Audio demo of my Synton Syrinx. This one has been serviced and the power input changed from 220 to 110V.

The Syrinx uses seven Curtis chips for its VCO's, VCF's and envelopes. It has two analog VCO's, a sub-oscillator and three flexible voltage-controlled filters. You can switch between the three filters for either a 24 dB lowpass, or two bandpass filters, and they can be patched in four different ways (series/parallel). Additionally the Syrinx has two LFO's, FM, PWM, osc-sync, 2 ADSR envelopes, ring modulation, portamento and a cool touch-pad that can control various parameters from pitch-bending to the LFO rate. The Syrinx's Mixer section lets you adjust levels for each VCO and the sub-osc as well as the Noise Generator and Ring Modulator. Unfortunately, being released around 1983, the Syrinx just missed out on MIDI and patch memory options.

Polyphony - Monophonic
Oscillators - 2 VCO's (tri, saw, square, PWM) plus 1 sub-oscillator, ring modulation and noise gen.
LFO - 2
Filter - 2 Bandpass filters (Peak 1 & 2) and 1 Lowpass 24dB/oct filter. Individual cutoff and resonance controls, ADSR Envelope, Keyboard Tracking and LFO modulation
VCA - 2 ADSR filters (one can modulate the VCF)
Keyboard - 44-keys (3 1/2-octave, no velocity, low-note priority)
Arpeggiator - None
Sequencer - None
Memory - None
Control - CV / Gate (Moog type). Touch 'N Bend Pad.
Date Produced - 1983/84"

Fraptools MAGNOLIA - (sounds only DEMO by gattobus)

video upload by gattobus and Frap Tools

"What is Magnolia? I’ve selected some patches I’ve created (except the second one, which is Giovanni’s from Fraptools) to give you an idea about it. Most of the sounds you hear are factory presets. I’m honoured and so proud to have been part of Magnolia’s creation. I tested the prototype for months and created some crazy programs with it.

Most of the FX you hear in the video are internal. No external FX were added except for a couple of patches; check the upper right corner of the screen for details."
